Design and Comparative Cost Analysis of Alternative Prefabricated Beef Cattle Barns with Conventional Barn Types

In this study, planning, design and cost analysis of prefabricated beef cattle barns carried out. Steel mesh was used to strengthen the foundation structure. Galvanized-sheet material as carrier cover material, shaped like a trapezoid cross-section. The barns, which are planned in form tunnel cross-section tie-stalls type, designed for 10, 20 30-cattle be particularly suitable family enterprises. Polyurethane (PU) foam extruded polystyrene sandwich panel (XSP) were provide heat sound insulation. Cost galvanized-sheet compared with constructed by traditional production method. After analyses, we found that number animals increased, barn per animal decreased. reduction rates PU insulated 30.1%, 32.7% 30.6% respectively. These values 24.9%, 27.8% 25.5% barn. most economical combination polyurethane insulation galvanized sheets. technically sufficient, economically advantageous than conventional ones, so it can recommended both newly established enterprises want improve their old barns.
